Ethyl 4-(1,3-dioxo-2,3-dihydro-1H-benzo[de]isoquinolin-2-yl)benzoate.

ABSTRACT: The title compound, C(21)H(15)NO(4), was synthesized by reducing the Schiff base obtained from acenaphthenequinone and ethyl-4-aminobenzoate. The dihedral angle between the essentially planar 1,3-dioxo-2,3-dihydro-1H-benzo[de]isoquinoline ring system [maximum deviation = 0.061?(2)?Å] and the benzene ring is 75.08?(10)°. In the crystal, mol-ecules are connected via weak inter-molecular C-H?O hydrogen bonds, forming a two-dimensional network. The ethyl group is disordered over two sets of sites with a refined occupancy ratio of 0.502?(12):0.498?(12).

Ethyl 2-[1,3-dioxo-6-(piperidin-1-yl)-2,3-dihydro-1H-benz[de]isoquinolin-2-yl]acetate.

Project description:In the title compound, C(21)H(22)N(2)O(4), the naphthalimide unit is almost planar (r.m.s. deviation = 0.081Å). The carboximide N atom and the five C atoms of the eth-oxy-carbonyl-methyl substituent also lie close to a common plane (r.m.s. deviation = 0.119Å), which subtends an angle of 71.06?(8)° to the naphthalamide plane. The piperidine ring adopts a chair conformation. In the crystal, inter-molecular C-H?O hydrogen bonds link the mol-ecules into zigzag chains along the a axis.

2-(tert-Butoxy-carbonyl-amino)-6-(1,3-dioxo-1H-2,3-dihydro-benzo[de]isoquinolin-2-yl)hexa-noic acid.

Project description:In the title naphthalimide derivative, C(23)H(26)N(2)O(6), the 1,8-naphthalimide system is essentially planar [maximum deviation = 0.0456?(16)?Å]. A characteristic pattern of alternating long and short C-C bond lengths is observed in the 1,8-naphthalimide unit. The mean planes through the methyl carbamate and acetic acid groups form dihedral angles of 42.30?(9) and 61.59?(9)°, respectively, with the 1,8-naphthalimide plane. In the crystal structure, inter-molecular O-H?O and C-H?O hydrogen bonds link neighbouring mol-ecules, forming R(2) (2)(9) hydrogen-bond ring motifs. These rings are further inter-connected by inter-molecular N-H?O and C-H?O hydrogen bonds into a three-dimensional supra-molecular network.

4-[(1,3-Dioxo-2,3-dihydro-1H-benzo[de]isoquinolin-2-yl)meth-yl]-N'-[(E)-4-nitro-benzyl-idene]benzene-sulfono-hydrazide dimethyl sulfoxide monosolvate.

Project description:The mol-ecular structure of the title compound, C(26)H(18)N(4)O(6)S·C(2)H(6)OS, shows an E conformation of the hydrazone double bond. The presence of a methyl-ene group between the benzo[de]isoquinoline and benzene-sulfonyl moieties allows the 4-nitro-phenyl ring and the benzo[de]isoquinoline system to be parallel with respect to each other, so that the mol-ecule adopts a U-shaped spatial conformation. The dihedral angle between mean planes of these aromatic groups is 4.4 (1)°. This special arrangement enables neighboring mol-ecules to be inter-calated, forming slipped π-π inter-actions [centroid-centroid distance = 3.535 (2) Å] between the 4-nitro-phenyl and benzo[de]isoquinoline groups and point-to-face C-H⋯π inter-actions between the benzo[de]isoquinoline and benzene-sulfonyl aromatic systems. In addition, the crystal packing also features an inter-molecular N-H⋯O inter-action involving the amine group and the dimethyl sulfoxide solvent mol-ecule.

Crystal structures of 2-meth-oxy-isoindoline-1,3-dione, 1,3-dioxoisoindolin-2-yl methyl carbonate and 1,3-dioxo-2,3-di-hydro-1H-benzo[de]isoquinolin-2-yl methyl carbonate: three anti-convulsant compounds.

Project description:The title compounds, C9H7NO3, (1), C10H7NO5, (2), and C14H9NO5, (3), are three potentially anti-convulsant compounds. Compounds (1) and (2) are isoindoline derivatives and (3) is an iso-quinoline derivative. Compounds (2) and (3) crystallize with two independent mol-ecules (A and B) in their asymmetric units. In all three cases, the isoindoline and benzoiso-quinoline moieties are planar [r.m.s. deviations are 0.021?Å for (1), 0.04 and 0.018?Å for (2), and 0.033 and 0.041?Å for (3)]. The substituents attached to the N atom are almost perpendicular to the mean planes of the heterocycles, with dihedral angles of 89.7?(3)° for the N-O-Cmeth-yl group in (1), 71.01?(4) and 80.00?(4)° for the N-O-C(=O)O-Cmeth-yl groups in (2), and 75.62?(14) and 74.13?(4)° for the same groups in (3). In the crystal of (1), there are unusual inter-molecular C=O?C contacts of 2.794?(1) and 2.873?(1)?Å present in mol-ecules A and B, respectively. There are also C-H?O hydrogen bonds and ?-? inter-actions [inter-centroid distance = 3.407?(3)?Å] present, forming slabs lying parallel to (001). In the crystal of (2), the A and B mol-ecules are linked by C-H?O hydrogen bonds, forming slabs parallel to (10-1), which are in turn linked via a number of ?-? inter-actions [the most significant centroid-centroid distances are 3.4202?(7) and 3.5445?(7)?Å], forming a three-dimensional structure. In the crystal of (3), the A and B mol-ecules are linked via C-H?O hydrogen bonds, forming a three-dimensional structure, which is consolidated by ?-? inter-actions [the most significant inter-centroid distances are 3.575?(3) and 3.578?(3)?Å].

1,3-Dioxo-2,3-dihydro-1H-isoindol-2-yl 2,3,4-tri-O-acetyl-?-d-xyloside.

Project description:The title compound, C(19)H(19)NO(10), was obtained from the reaction of ?-d-1-bromo-2,3,4-tri-O-acetylxylose with N-hy-droxy-phthalimide in the presence of potassium carbonate. The asymmetric unit contains two independent mol-ecules, in which the O-CH-O-N torsion angles are 73.0?(4) and 65.0?(4)°. The hexa-pyranosyl rings adopt chair conformations and the substituent groups are in equatorial positions. In the crystal, mol-ecules are linked by nonclassical C-H?O hydrogen bonds.

5-Ethyl-4a-meth-oxy-1,3-dimethyl-4a,5-dihydro-benzo[g]pteridine-2,4(1H,3H)dione.

Project description:The title compound, C(15)H(18)N(4)O(3), was formed by the reaction of methanol with 5-ethyl-1,3-dimethyl-alloxazinium perchlorate. Its structure mimics those of possible flavin inter-mediates in flavoenzymes. The heterocyclic rings are substituted with methyl, ethyl and meth-oxy groups. The central tricyclic skeleton is bent due to the presence of an sp(3) C atom. There are weak inter-molecular C-H?O inter-actions in the structure, forming a three-dimensional network.
